If you process the current-group() with e.g.
  <xsl:for-each select="current-group()">
    <xsl:variable name="pos" select="position()"/>
    <xsl:variable name="prec" select="current-group()[position() lt 
$pos]"/>
    <xsl:variable name="foll" select="current-group()[position() gt 
$pos]"/>
     ...
  </xsl:for-each>
or use the same approach with <xsl:apply-templates 
select="current-group()"/> then you can access the items in a group 
preceding or following the current item in the group.
